[Room air quality and ventilation].
In a test chamber of 30 m3 the air pollutants caused by man were measured. Variables were: number of persons and their activities and the rate of the air change. During test sessions of two hours the temperature, the relative humidity, the carbon dioxide and the intensity of odors were measured. There was a significant correlation between the odor intensities and the concentrations of carbon dioxide-independent of the number of persons and the air change rate. At air change rates of 12-15 m3 per person and per hour, the carbon dioxide concentration was not higher than 0.15% and the odor intensity was evaluated only as a slight annoyance. Further experiments were performed with physical activity and smoking.
